从日期时间选择器获取日期和日期之间的值 [英] Getting values between from and to date from datetimepicker

问题描述

我的程序中有 2 个日期时间选择器.一种是指定从，另一种是指定到.我试图在 from 和 to 之间获取值.我在查询之间传递了 2 个 datetimepicker 的值，但我只获取了一个月日期之间的值.如果我从一个月的日期中选择并从另一个日期中选择，则不会显示数据.

SqlDataAdapter da3 = new SqlDataAdapter("SELECT Name from Billing WHERE Bill_Date between @From AND @To", con);da3.SelectCommand.Parameters.AddWithValue("@From", dateTimePicker_FromSaleReport.Text);da3.SelectCommand.Parameters.AddWithValue("@To", dateTimePicker_ToSaleReport.Text);数据表 dt3 = 新数据表()；da.Fill(dt);dgv_FromToSaleReport.DataSource = dt3;

解决方案

你必须为 Text 传递 DateTime 对象，所以首先你必须从 DatePicker 获取 DateTime 值，然后继续:

>

DateTime fromDate, toDate;DateTime.TryParse(dateTimePicker_FromSaleReport.Text, out fromDate);DateTime.TryParse(dateTimePicker_ToSaleReport.Text, out toDate);//如果您知道输入日期的格式，请使用 DateTime.TryparseExtractSqlDataAdapter filterAdapter = new SqlDataAdapter("SELECT Name from Billing WHERE Bill_Date between @From AND @To", con);filterAdapter.SelectCommand.Parameters.Add("@From",SqlDbType.DateTime).value = fromDate;filterAdapter.SelectCommand.Parameters.Add("@To", SqlDbType.DateTime).value = toDate;数据表filteredTable = new DataTable();filterAdapter.Fill(filteredTable);dgv_FromToSaleReport.DataSource = 过滤表；

注意:请确定数据库中的列类型，应该是DateTime才能进行比较.

I have 2 datetimepickers in my program. One is to specify from and other is to specify to. Iam trying to get values between from and to. I passed values of 2 datetimepicker to between query but iam getting only values between a months date. if i select from date of a month and select to from another date is wont display datas.

SqlDataAdapter da3 = new SqlDataAdapter("SELECT Name from Billing WHERE Bill_Date Between @From AND @To", con);
da3.SelectCommand.Parameters.AddWithValue("@From", dateTimePicker_FromSaleReport.Text);
da3.SelectCommand.Parameters.AddWithValue("@To", dateTimePicker_ToSaleReport.Text);
dataTable dt3 = new DataTable();
da.Fill(dt);
dgv_FromToSaleReport.DataSource = dt3;

解决方案

You have to pass the DateTime object instead for Text, so first of all you have to get DateTime value from the DatePicker, and then proceed with that:

DateTime fromDate, toDate;

DateTime.TryParse(dateTimePicker_FromSaleReport.Text, out fromDate);
DateTime.TryParse(dateTimePicker_ToSaleReport.Text, out toDate);

// use DateTime.TryparseExtract if you know the format of input date

SqlDataAdapter filterAdapter = new SqlDataAdapter("SELECT Name from Billing WHERE Bill_Date Between @From AND @To", con);
filterAdapter.SelectCommand.Parameters.Add("@From",SqlDbType.DateTime).value = fromDate;
filterAdapter.SelectCommand.Parameters.Add("@To", SqlDbType.DateTime).value = toDate;

DataTable filteredTable = new DataTable();
filterAdapter.Fill(filteredTable);
dgv_FromToSaleReport.DataSource = filteredTable ;

Note : please be sure about the type of column in the database, It should be DateTime in order to performs the comparison.
